Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If beam-based communication is used to improve data rate and spectral efficiency, then communication performance is enhanced, but beam failure becomes more frequent and difficult to manage

Engineering Contradiction:

Improvedata rateVSAvoidbeam failure

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system proactively manages beam failures by pre-configuring failure instance tracking and grant invalidation mechanisms. When beam failures are detected, the system automatically invalidates associated grants and manages resources before complete communication breakdown occurs, rather than reacting after failure

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms to track beam failure instances and their associated grants. By monitoring failure instances and maintaining state information about invalid grants, the system continuously adapts its resource allocation based on observed beam failure patterns and communication conditions

Inventive Principle:

Principle #23Feedback

2Reliability

If beam failure instances are tracked and grants are invalidated to improve communication reliability, then beam failure management is enhanced, but system complexity increases

Engineering Contradiction:

Improvebeam failure managementVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system manages its own complexity through self-service mechanisms where beam failure instances automatically associate with their grants, and the network device autonomously tracks and invalidates grants based on detected failure instances. The system serves itself by maintaining internal state information without requiring external management overhead

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system segments beam failure management by tracking individual failure instances and their associated grants separately. Each beam failure instance is managed independently with its own state tracking, allowing granular control over grant invalidation and resource allocation without requiring system-wide complexity

Inventive Principle:

Principle #1Segmentation

AI summary

Provided are a method by which a first device performs wireless communication and an apparatus for supporting same. The method may comprise the steps of: obtaining information about an instance related to beam failure; on the basis of obtaining the information about the instance related to the beam failure, determining grant related to the instance related to the beam failure as invalid grant; starting a timer related to the invalid grant; and on the basis that the timer related to the invalid grant expires, determining the invalid grant as valid grant.
